so I'm tinkering with ipv6 again, using Hurricane Electric to set up a tunnel
over Comcast. it wasn't working, and I noticed an ipv6 address in the 2002/16
block on wlan0. wtf? had to sudo sysctl net.ipv6.conf.wlan0.autoconf=0, and restart networking, to get rid of it. now I can apparently ping6 the other end of
the tunnel, but no luck with test-ipv6.com (unknown host) or ipv6.google.com (no route) yet.
